Hi, It is our first project with arduino and we need to read a couple of values obtained from Analog input ports of the Leonardo board and then send those values vía i2c to a Ni MyRio board.
We are able to obtain the sensor values and also we have settled communication between both boards using i2c but we just know how to send "hello". Any ideas?
Thanks for your help.

Well,instead of sending hello, send the values.
You can either build them into c-strings (char arrays) with sprintf() to build the sting and send that or send the 2x2 bytes of you analog read directly without building a text representation (See the write command)
